Definitions
- the invention is based on a method for requesting Pages in teletext according to the preamble of claim 1.
- All page request methods (page number, page "+/-", Fl-oF, Top) are page numbers oriented i.e. the acquisition circle of the respective decoder is entered manually by the transmitter suggested Top / FloF page numbers, or by the user entered page numbers. The incoming page numbers are then compared to the programmed page numbers and read the full page if they match.
- EP-A-0 567 185 describes a method for requesting Teletext pages known, where the incoming Teletext pages can be searched for a search term. For this, the a shift register for the currently arriving teletext page fed and by a comparator with the desired one Search term compared in another register. The Teletext pages with your search terms or theirs Page numbers are used for later viewing or Selection saved.
- the invention has for its object a simple To create procedures for requesting teletext pages. This Task is by the features specified in claim 1 Invention solved. Advantageous developments of the invention are specified in the subclaims.
- the request is done by typing of a search term.
- This search term can consist of letters as well Numbers.
- This Areas can be vacant after the search term is found selectable criteria can be evaluated and if necessary then the page and / or the search word and / or it can specific areas are displayed.
- the relevant page is displayed.
- the word you are looking for is preferably highlighted in color or otherwise marked. Then there is the possibility of the next page with the same Search term to request which in time where a page is already being searched.
- FIG. 1 shows the acquisition unit ACQ with the incoming data from the teletext decoder DTD, a data output and an address output.
- the data arrive via a data line DA in a shift register SR, which has two data outputs.
- These data outputs are connected to a comparator V and a memory interface SI by data lines DA.
- the address output of the acquisition ACQ is connected to the memory interface SI by an address line ADR.
- the memory interface SI passes the address to the memory S via an address line ADR, the data via data lines DA and the signal via the line WE.
- the character memory ZS is connected to the comparator V and receives a signal from the I 2 C bus I.
- the comparator V is connected to the memory interface SI and a display control unit AKE.
- the display control unit AKE is connected to the display unit B and the memory interface through data lines DA.
- the user enters a search term using the remote control.
- This search term is stored in the character memory ZS.
- the acquisition unit ACQ receives the data from the teletext decoder DTD. This data is transferred to the shift register SR.
- the comparator V now compares the data of the character memory ZS and the data of the shift register SR. If the corresponding page is present, the comparator forwards the information to the display control unit AKE and to the memory interface SI that a page with the search term is available.
- the shift register SR then forwards the data to the memory interface SI.
- the memory interface SI forwards the data into the memory and to the display control unit AKE.
- the data from the AKE display control unit are then displayed on the screen. If no teletext page was found, it will be displayed on the screen.
- the signal from the I 2 C bus I is fed to the acquisition page organizer ACQPM and the character memory ZS.
- the teletext decoder DTD gives the signal for acquisition ACQ.
- the data arrive in a shift register SR and via line L1 in the acquisition address generator ACQAG.
- the address generator ACQAG also receives a signal via line L3 from the acquisition side organizer ACQPM.
- the acquisition address generator ACQAG forwards the address Addr thus created to the memory interface SI.
- the memory interface SI receives information from the slide register SR via the data line.
- the memory interface SI passes on the information about the memory S via the address control AddrC line and the data line.
- the user requests a character string, it is stored in the character memory Zs and the comparator V compares the content of the shift register SR with the character memory Zs. If a page with the corresponding term has been found, this information is passed on to the acquisition page organizer ACQPM via line L2 given. This unit gives the information to the acquisition address generator ACQAG via the line L3 and the information is stored with the address via the line Addr and the line Data in the memory interface SI and then in the memory S.
- the display generator DG contains the character generator CharGEN with an RGB output, a display address generator DispAG and a display page organizer DisplPM with an output L1 and an output for memory number L3 and an input from I 2 C bus I.
- the display address generator DispAG outputs the address line Addr that Addresses to the memory interface I on.
- the memory interface SI forwards the page data PD to the shift register SR.
- the comparator V compares the pages of the shift register SR with the character memory ZS and outputs the information about an identical character in one page to an AND gate AND via the output L2.
- the AND element AND also receives the page data PD and forwards them to the character generator CharGEN.
- the data can be displayed in this way.
- the memory interface SI receives its data from the memory S after it has been requested via the address control line AddrC.
- the user gives his Search term and the teletext system searches various Programs based on this search term. That way it is possible to search for a desired film in the long run and if the search is successful, even after a long period of time communicated the result of the search to the user. In a before selectable rhythm, it is possible to output a result to bring about either the result or the User brings the message that the search is currently Not was successful.
- search terms based on the same as before explained can be entered, i.e. daily the user is e.g. the weather information, a heading feature film and e.g. the films with actor Heinz Johmann selected.
- the user is e.g. the weather information, a heading feature film and e.g. the films with actor Heinz Johmann selected.
- This training it is possible an individual offer from the teletext pages to have a search. The user in this way allows you to put together your own every day Quickly display teletext information.

Fig. 2 zeigt ein Blockschaltbild zum Einlesen der Daten. Das Signal vom I2C Bus I wird dem Acquisationsseitenorganisator ACQPM und dem Zeichenspeicher ZS zugeführt. Der Teletextdecoder DTD gibt das Signal zur Acquisation ACQ. Von der Acquisation ACQ gelangen die Daten in ein Schieberegister SR und über die Leitung L1 in Auquisationsadressengenerator ACQAG. Der Adressengenerator ACQAG erhält weiterhin ein Signal über die Leitung L3 von dem Acquisationseitenorganisator ACQPM. Der Acquisationsadressengenerator ACQAG gibt die so erstellte Adresse Addr an das Speicherinterface SI weiter. Das Speicherinterface SI bekommt über die Leitung Data Informationen vom Schieberregister SR. Das Speicherinterface SI gibt über die Leitungung Address control AddrC und über die Leitung Data die Informationen zum Speicher S weiter. Fordert der Benutzer eine Zeichenfolge an, so wird diese im Zeichenspeicher Zs abgespeichert und der Vergleicher V vergleicht den Inhalt des Schieberegisters SR mit dem Zeichenspeicher Zs. Wenn eine Seite mit dem entsprechenden Begriff gefunden wurde wird diese Information über die Leitung L2 an den Acquisationsseitenorganisator ACQPM weiter gegeben. Diese Einheit gibt über die Leitung L3 die Information an den Acquisationadressengenerator ACQAG und die Informationen werden mit der Adresse über die Leitung Addr und die Leitung Data im Speicherinterface SI und anschließend im Speicher S abgelegt.
